mechanism, or both.

Accordingly, one of the objects of this invention is to provide adilator device with- -in the treating end of which is provided both `aheating element and also a vibrator mechanism, either one or both ofwhich mayl be rendered operative, at the-will of the person using thedevice. Preferably, the heating action is effected by means of anelectric heating coil, and the vibrator mechanism is also of anelectrically operated design, whereby suitable external switch means maybe operated for controlling .the \circuit through either or both of thecircuits containing the heating element and the vibrator mechanism.

Itis a further object of the invention to provideI a dilator casing ofthe character described, and having its open end, by which it ismanually operated, so extended as to provide a handle portion ofsufficient length to facilitate the manipulation of the device, as ineffecting ,massaging movements.

With these general objects in view, the invention will now be describedby reference to the accompanying drawing illustrating.

one form of construction which I have devised for embodying the proposedimprovements, after which those features deemed to be novel will beparticularly set forth and claimed.

In the drawing--- Figure 1 is a plan View of a dila'tor constructionembodyingthe proposed features of improvement;

Figure 2 is a-central` longitudinal sectional view of the same,theelectric socket member being omitted;

Figure 3 is a view of that end of the device to which connection is madeto the electric socket;

Figures 4 and 5 are transverse sections,

' taken on the lines IV--IV and V-V, respectively, of Figure 2, but onan enlarged scale;

Figure 6 is a wiring diagram, showing the electric circuit to theelectric heating element and the vibrator mechanism.

Referring now to the drawmg in detail,

this illustrates a hollow dilator casing 8 havend of the casing, forlimiting the application of the device into operative position, andleaving a handle portion 12 between said flange and the open end of thecasing of a length sufficient for facilitating the manipulation of thedevice by the operator, as in massaging operations. Between the externalflange and closed end 9 of the casing, the latter is formed with anexternal enlarged portion 14 tapering in opposite directions, and alsoserving to facilitate the application of the device into operativeposition as well as tending to oppose any casual withdrawal of thedilator from itsposition of use.

lVithin the interior of the casing 8 is designed to be inserted aheating coil and vibrator assembly comprising a frame member 15 somewhatrectangular in cross soction and adapted to lit snugly within thecasing, one end of this frame member being provided with a screw 16carrying a spool 17 on which is mounted the heating coil 18, which isthus brought within the closed enlarged end 9 of the casing, as shownclearly in Figure 2v. 1

lVithin the frame member 15 is also mounted a vibrator coil 20 adjacentto the heating coil 18, with one end of the coil in position forattracting a Vibrator element 21 which is mounted upon a pivot pin 22and actuated by a coil spring 23 on said pinA 22 in a direction forretracting the vibrator 21 from the coil 20, as shown in Figure 2. Inthis retracted position, the vibrator element 21 closes the vibratorswitch contacts 24, as shown in Figures 2 and 6, whereby the circuit isclosed thru coil 20.

As shown by the circuit diagram in Figure 6, both the vibrator coil 20and the heating coil 18 are connected with aA conductor 25 mg a slightlyenlarged oval portion 9 at' its i closed end, and a suitable annularflange 10- at some dlstance from the opposite or closed leading to oneof a set of posts 26 which is '35 in Figure 4:) is also provided with aconductor 34 leading to the third post 26 which is connected by aconductor 36 to a second switch contact 37, as shown in Figure 6. As

, will be readily understood, by the operation of the switch element 38shown in Figure 6, the circuitmay be closed through either the heatingcoil I18 by moving the switch 38 into the position shown, or through thevibrator coil 2() by moving the switch 38 into its opposite position, orin engagement with only the switch Contact 37; whereas, by leaving theswitch 38 in central position, thatis, engaged with both the contacts 33and 37 the `'circuit is thus closed through both the coil 18 and thecoil 20 for the simultaneous operation of both the heating coil and thevibrai actuating the vibrator mechanism, or for effecting thesimultaneous operation of both coils, as may be desired for exerting theparticular therapeutic eiiect desired. This) vibratory action of thevibrator device, in addition to the heating effect of the coil 18,exerts a stimulative action upon the glands in the vicinity of thedilator casing when in operative position, and the usefulness of A thedevice is further increased by the provision of the extension 12 betweenthe flange 10 and the open end of the casing 8, where'- by the dilatormay be more effectively manipulated by the operator in the exercise ofmassaging movements.

'The construction shown and described is of a comparatively simplecharacter, comprising relatively few parts of a nature not likely to getout of order, and which may be readily removed for repair if necessaryand the construction as a Whole is of a character adaptedto bemanufactured at small expense. A

While I have illustrated and described what I now regard as thepreferred form of construction for embodying the proposed improvements,I desire to reserve the right to make-all such changes or modificationsas may fairly fall within the scope of the appended claims.

What I claim is:

l. A dilator comprising a hollow casing closed at one end and open atits other end, an electric vibrator mechanism within the closed end ofthe casing and comprising a frame member mounted within said casing, anelectric vibrator coil mounted in said frame, a vibrator elementassociated with said coil and operating by impact alternately againstone end of said coil and the adjacent portion of said frame, and anexternal switch for controlling the circuit through said mechanism.

2. A dilator for internal application, comprising a hollow casing closedat one end and open at its other end, a frame member comprising a pairof parallel arms extending into the casing, .an electrical heating coilcarried by the extremities of saidarms, a vibrator coil carried by onearm vibrator mechanism for cooperation With said vibrator coil, and asinglekswitch arranged for separately or simultaneously controlling saidheating and vibrator coils.

In witness whereof I hereunto alix my signature. ,e
